CABLE CUTTER Application filed October 2, 1929.

This invention relates to improvements in cutters, particularly to acable cutter, and it is the principal object of my invention to providea cutter for the leaden mantles of cables preventing damage to the cablewires and injury to the workmen.

Another object of my invention is the provision of a cable cutterallowing a convenient adjustment of the rollers carrying the cutterknives to the respective cable thickness.

Still another object of my invention is the provision of a cable cuttingdevice of comparatively simple and therefore inexpensive construction,yet durable and eflicient in its operation.

A further object of my invention is the pro vision of a cable cutterequipped with a suitable frame having a handle for the convenientmanipulation of the device.

A still further object of my invention is the provision of a cablecutter, the knife carrying rollers of which are arranged on shafts journaled in bearings which can be adjusted in vertical direction to suitthe distance between the knives to the thickness of the lead cablemantle to be out.

These and other objects and advantages of my. invention will become morefully known as the description proceeds and will then be specificallydefined in the appended claim.

In the accompanying drawing, forming a material part of this disclosure:

Fig. 1 is a plan view of a cable cutting device constructed according tomy invention. Fig. 2 is a side elevation thereof.

Fig. 8 is a rear end view of the cable cutter. Fig. 4 is a section online 4l4 of Figure 3. As illustrated my cable cutter comprising a frame10 having a rear wall 11, two preferably steel rollers 13 and 14 arearranged on shafts 15 and 16 respectively so as to rotate in oppositedirections. These rollers are thicker at their ends and have a reducedcentral diameter.

The rollers carry each two knives 17 and 18 one on each side of theircentral part, keyed thereto as at 19.

The ends of shafts 15 and 16 are journaled in bearings 20, 21,respectively, through which 59 are guided two threaded vertical rods 22,and

Serial No. 396,707.

23, respectively having an upper part formed with left hand thread and alower part provided with right hand thread and held in the bottom bar offrame 11 and extending with their upper ends above the upper bar offrame 11 where they carry adjusting Wing or other nuts 24:, 25,respectively. The rollers are held on their shafts by means of setscrews 26 or the like.

The operation of my device will be readily 60 understood from the abovedescription and simultaneous inspection of the drawing, and it will beclear that the distance between the rollers and their knives may besuitably adjusted by the proper operation of nuts 24:, 25, to suit therespective thickness of the leaden cable mantle to prevent cutting ofthe wires therein.

It will be understood that I have described one form of my inventiononly and that I may (0 make such changes therein as come within thescope of the appended claim without departure from the spirit of myinvention.

What I claim as new and desire to secure by Letters Patent is:

In a cable cutter of the class described, a frame, a front handletherefor, a rear frame integral with said frame, bearings in said rearframe, shafts journalled in said bearings, rollers having larger enddiameters and a smaller centre diameter on said shafts, a pair of kniveson each roller, one on each side of the center thereof, and means foradjusting the distance between said knives to suit the thickness of thelead mantle of a cable to be cut to prevent cutting of the core wires.

In witness whereof I have signed my name WILLY GROTE.

to this specification.
